Abstract
Disclosed is a system including a flow control assembly. The system may include a flow regulating shunt system, for various purposes. The flow control assembly may be controlled according to selected parameters and methods.
Claims22
A flow and/or pressure regulating assembly for a hydrocephalus shunt system, the regulating assembly comprising:
- a reservoir having a reservoir inlet and a reservoir outlet;
- a controller;
- a valve seat;
- a valve member configured to be supported relative to the valve seat to regulate flow into the reservoir through the reservoir inlet;
- and
- an actuator in response to an actuator signal from the controller to move between an activate position and an inactivate position;
- wherein the actuator is selectively positioned in the active position or the inactive position to assist in the valve member regulating the flow into the reservoir.
A flow and/or pressure regulating assembly for a hydrocephalus shunt system, the regulating assembly comprising:
- a valve seat;
- a valve member configured to be supported relative to the valve seat to regulate flow into a reservoir;
- an arm support member, wherein the arm support member is configured to bias the valve member in a closed position relative to the valve seat;
- a substrate positioned on a side of the arm support member away from the valve member;
- and
- an actuator formed from and on the substrate;
- wherein an effective support length of the arm support member determines a biasing force on the valve member and the actuator is selectively positioned in an active position or an inactive position to select the effective support length.
A method of configuring a flow and/or pressure regulating assembly for a hydrocephalus shunt system, the method comprising:
- positioning a valve member within a reservoir to be biased relative to a valve seat;
- supporting and biasing the valve member in a closed position relative to the valve seat with an arm support member;
- providing an actuator formed from and on a substrate near the arm support member;
- and
- configuring the actuator to be selectively positioned in an active position or an inactive position relative to the arm support member to assist in achieving a selected biasing force applied to the valve member.
